FENCE.

SPECIFICATION forming part of Letters Patent No. 671,021, dated April 2, 1901.

Application filed .Tune 5, 1900.

To @ZZ whom t may con/cern.-

Be it known that I, RoLLv W. JACKSON, a citizen of the United States, residing at Newman, in the county of Douglas and State of Illinois, have invented certain new and useful Improvements in Fences; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to fences, and it has particular relation to that class of fenceswhich embody line-wires, metallic posts, and concrete post-bases.

The object of my invention is to provide a simple and improved fence of this class which will be especially advantageous in points of durability, strength, ease and inexpensiveness of manufacture and construction, convenience, adaptability in its uses, effectiveness, and general efficiency.

In the drawings, Figure l is a perspective View showing a portion of a fence embodying my improvements. Fig. 2 is a top or plan view. Fig. 3 is a detail vertical sectional view of the post. Fig. 4 is a detail horizontal sectional view taken on the line a: tr, Fig. 4. Fig. 5 is a detail horizontal sectional view taken on the line y y, Fig. 4c. Fig. 6 is a detail horizontal sectional view taken on the line e z, Fig. 4. Fig. 7 is a plan view of the metallic plate or blank from which the post proper is formed.

Corresponding parts in all the views are denoted by the same numerals of reference.

Referring to the drawings, l designates the posts proper, which are construct-ed of metal and mounted in bases 2, formed of concrete or, analogous non-corrosive material,the metallic post being protected by the base against contact with the ground and consequent decay. The post is preferably constructed of a plate bent or forged into shape and comprises two wings 3 3, extending longitudinally with respeel: to the post and projecting relatively at angles to each other. In cross-section the wings 3 may form an L or a V, the V shape being preferred for the line-posts and the L shape being best adapted for the posts at the fence-corner construction. The lower end of the post is simply embedded in the top portion of the base 2 and is retained by the setting of the latter.

Serial No. 19,129. (No model.)

It will be noted that the angular wing shape of the post forms a very strong construction which is inherently braced against buckling and enables the construction of the post conveniently and inexpensively of a comparatively thin plate. The line-posts preferably taper, as shown at 4c, so that they are approximately shaped vertically, providing a broad base portion 5, tapering to a narrower top 6, by which economy in material without affecting required strength is insured.

At the vertex of the angle formed by the wings 3 the post is provided with transverse slots or openings, as at 7, arranged in vertical series and forming keepers for the linewires 8 of the fence, which line-Wires pass through said openings 7. The slots 7 intersect the middle edge 9 of the post and the adjacent portions of both wings 3, as shown. All of the line-wires S are retained in the keeper-openings 7 at each post after they are passed or strung through said openings by means `of a single post-key formed by a wire 10, extending longitudinally with relation to the series of keeper-openings 7 and line-wires 8 and from top to bottom of the post, said key-wire l0 being seat-ed in the vertex of the angle formed by the wings 3 at the inner side of the middle edge 9 of the post. The wire 10 closes the outer side of the keeperopenings 7 at the vertexof the angle and prevents the line-wires 8 from being drawn outwardly from said slots or openings, the wire l0 being itself retained against outward 'movement by bearing against the walls of the of said base.

It will be noted that the general construction and arrangement is such that the keywire lO may, if desired, be adapted to be withdrawn vertically from the post, which would enable a whole section of the fence to be opened-up by releasing the line-wines 8 from the keeper-openings 7 without moving or disturbing said wires 8 in their longitudinal arrangement in the fence-construction, and in like manner the set of *wires 8 could IOO be again seated in theslots 7 and locked in position by a simple insertion of the key 10. To facilitate this removal or insertion of the key 10, it may be provided with a head, as at 14, normally projecting above the top of the post. Y

In the practical construction of the post proper it is simply necessary to take a sheet or blankof required shape and thickness, (see Fig. 7,) consisting of rolled metal, and form the slots or openings 7 by punching or otherwise and then press or forge the plate into the required angular shape forming the wings 3. The metallic post thus formed may then be galvanized by dipping.

In the practical construction of the base 2 of concrete or cement or similar material it is only necessary to mix a mortar (preferably of cement and crushed stone or gravel) and place the same in a suitable or adapted mold. The lower end of the post is then set into the mortar in the mold, when the whole is permitted to stand until the mortar sets, and the base of the completed post is then removed from the mold. The base 2 is preferably of tapering` form toward its top, as shown at 15, which aifords a firmer hold against displace ment in the ground and enables more convenient detachment from the mold after the base has set or hardened, with the post proper in attached position. The bottom 16 and top 13 of the base 2 are preferably fiat, as shown.

A particular advantage insured by the improved construction and arrangement comprised in my invention and improvements as hereinabove described exists in the fact that pressure or strain upon the line-wires 8 between posts will not result in sagging of the Wires, there being a free movement of all the wires 8 longitudinally throughout the'fence between the corner or anchor posts. In this connection it will be noted that the line-wires 8 are not secured in their longitudinal relation to the line-posts, but merely pass through the same, (they being, however, effectively supported at each line-post,) and the tension with respect to the line-wires is therefore longitudinal from one end of the fence to the other between the corner or anchor posts.

being preferably of the L-shape cross-section,

as hereinbefore mentioned. Facing each Wing 3 ofthe post 17 I provide a brace-post 18, which is also preferably of L shape in cross-section, and one wing` 3 of each of said brace-posts preferably extends substantially parallel with a wing 3 of the corner-post. From the respective wings 3 of the post 17 extend brace-rods 19 19, respectively, to one of the wings 3 of the respective two brace posts 18. These brace-rods 19 are provided at both the top and bottom of the posts 17 and 18 and extend between the same on a direct longitudinal plane with relation to the Afence-sections. From the vbrace-connection wing 3 of each brace-post 18 at the top similar bracerods 20 extend downward to the respective wings 3 of the corner-post 17 at the bottom. The construction and arrangement just described form a thoroughly-braced corner or angular construction, which meets the longitudinal tension of the line-wires 8 of the fence-sections and affords a maximum degree of strength and security and will not buckle under strain. The linewires 8 of the respective fence-sections pass through openings 2l in the wings 3 of the posts 18, which project at right angles to the braceconnect-ion wings of said posts to which the brace-rods 19 and 20 are connected, and the wires 8 then extend to the corner-post 17 and have their ends securely maintained in connection with the respective wings 3 of said post 17 which wings are respectively parallel with the wings of the brace-posts, through which latter wings the line-wires pass. It will be noted that the construction and arrangementof the posts 17 and 18 and their connection-braces in relation to the line-wires are suoli that strain on any of the line-wires of the series extending from top to bottom of the fence will be met at the bottom portion of the corner-post 17, which is the point of greatest strength.

The advantages of my invention and improvements are apparent, and it is obvious that the fence is adapted for inexpensive manufacture, ease of construction, convenience in use, and effective and durable service under variable conditions.

I do not restrict myself to the precise details of structure and arrangement as herein shown and described, as variations andmodifications can manifestly be made within the scope of my improvements, and I therefore reserve the right to all such variations and modifications as properly fall within the spirit and scope of my invention and the terms of the following claims. Y

Having thus described my invention, I claim and desire to secure by Letters Pat- 611t- 1. An improved fence, comprising lineposts, a corner or anchor post consisting of divergent body-wings, brace-posts consisting of divergent body-Wings, one body-wing of each of said brace-posts extending'substantially parallel with a body-wing of the corner or anchor post, brace-rods extending between the body-wings of the corner-post and the body-wings of the brace-posts, and the linewires secured to the respective Wings of the corner-post and slidably sustained in free longitudinally-movable position by the respective parallel body-wings of the braceposts and by the line-posts.

2. An improved fence, comprising lineposts, a corner or anchor post consisting of divergent body-wings, brace-posts consisting of divergent body-wings, one body-wing of each of said brace-posts extending substantially parallel with a body-wing of the corner or anchor post, the line-wires secured to the respective wings of the corner-posts and slidably sustained in free longitudinally-mov- IOO IIO
